A unit test is a piece of code written by a developer that exercises a very small, specific area of functionality of the code being tested. This tutorial provides an overview of the unit test process and looks at the types of frameworks that are used in the unit testing phase of development.

- [Voiceover] As a developer, I always try…to write readable, bug free code.…Most of the time, I have a good idea what…the code should do based on the application requirements.…I build my classes, add properties and methods,…and I attempt to write the code that I think meets…the requirements or use history.…At some point I need to test the code…to see if it meets my expectations.…Does it do what it's supposed to do?…Code also needs to go through integration tests…to make sure it performs well with…the other parts of the application.…

Then there is the suite of other tests that are performed…on code, performance testing, regression testing, UI tests,…and user acceptance tests.…But before the code is put through the testing gauntlet,…every developer does some form of code verification test.…The customary name for this type of code test is unit test.…Unit testing is done by programmers, for programmers.…It's something we do for our benefit.…And at its most basic, it helps verify…our code as working correctly.…Here's an example, this C Sharp library named brokerage lib…

Ensure your code is up-to-par by performing a unit test, verifying your code works as expected. You can perform unit testing using Visual Studio 2015. Selecting a framework and creating a small piece of code, to exercise a specific area of functionality, is all you need to get started. In this course, learn about the types of frameworks, naming conventions, integrations, and options available to you and how to implement them into your testing workflow. Join Walt Ritscher as he explains the process and step-by-step instructions. Along the way, he provides guidance on how to test with multiple parameters, customize your test runs, discover untested code, and even debug the actual unit tests.

Topics include:

Examining types of frameworks

Choosing a naming convention

Creating unit tests

Running unit tests with Visual Studio

Modifying and correcting code

Handling exceptions

Installing and using nUnit
